Editor Syntax Maintenance

Dang has syntax definitions for three editors. When the language grammar changes (keywords added/removed, tokens renamed, new constructs), all three must be updated in sync.

Locations

VSCode

•editors/vscode/syntaxes/dang.tmLanguage.json — TextMate grammar
•Lives in the main repo (not a submodule)
•Keywords are in the keyword-control pattern as a \b(...)\b regex

Zed

•editors/zed/languages/dang/highlights.scm — tree-sitter highlights
•Submodule pointing to https://codeberg.org/vito/zed-dang
•Commit inside the submodule first, then update the submodule pointer in the parent repo

Neovim

•editors/nvim/queries/dang/highlights.scm — tree-sitter highlights
•Submodule pointing to https://codeberg.org/vito/dang.nvim
•Commit inside the submodule first, then update the submodule pointer in the parent repo

Tree-sitter highlights (Zed + Neovim)

The two .scm files are nearly identical but use different capture names (Zed uses @keyword.control, @variable.special, etc.; Neovim uses @keyword, @variable.builtin, etc.). Edit both when making changes.

Keywords are listed as (foo_token) nodes inside [ ... ] @keyword blocks. To add or remove a keyword, add or remove the corresponding (foo_token) line in both files.

TextMate grammar (VSCode)

Keywords live in the keyword-control repository entry as a single regex. To add or remove a keyword, edit the \b(...)\b alternation.

Committing

Since Zed and Neovim are submodules:

bash

# 1. Commit in each submodule
cd editors/zed && git add -A && git commit -m "..." && cd ../..
cd editors/nvim && git add -A && git commit -m "..." && cd ../..

# 2. Commit submodule pointers + VSCode changes in parent
git add editors/zed editors/nvim editors/vscode/syntaxes/dang.tmLanguage.json
git commit -m "chore(editors): ..."

Checklist

When a language keyword or token changes:

• Update editors/zed/languages/dang/highlights.scm
• Update editors/nvim/queries/dang/highlights.scm
• Update editors/vscode/syntaxes/dang.tmLanguage.json
• Commit submodules, then parent repo
